An empty barometric tube 1 m long is lowered vertically (mouth downwards) into a tank of water. What will be the depth above the water level in the tube, when the water has risen 20 cm inside the tube ? Take atmospheric pressure as 10.4 m column of water.

Water rises to a height of 10.3 cm in a capilaary of height 18 cm above the water level. If the tube is out at a height of 12 cm in the capillary tube

A glass capillary tube (closed from tap) of inner diameter 0.28mm is lowered vertically into water in a vessel. The pressure in the capillary tube so that water level in the tube is same as that in the vessel is N//m^(2) is (surface tension of water =0.7N//m and atmospheric pressure =10^(5)N//m^(2) .

A glass capillary tube of inner diameter 0.28 mm is lowered vertically into water in a vessel. The pressure to be applied on the water in the capillary tube so that water level in the tube is same as the vessel in (N)/(m^(2)) is (surface tension of water =0.07(N)/(m) atmospheric pressure =10^(5)(N)/(m^(2))

When a capillary tube is lowerd into water the mass of the water raised above the outside level is 5 gm. If the radius of the tube is doubled the mass of water that raises in the tube above the outside level is

A water tank is 20 m deep . If the water barometer reads 10 m at the surface , then what is the pressure at the bottom of the tank in atmosphere ?

If a capillary tube of diameter 0.4 m is dipped vertically into water, then the height to which water rises in the capillary tube will be ,
